I'm using pnpm in my project.

Error: Dependencies lock file is not found in /home/runner/work/lighthouse-ci-datadog-action/lighthouse-ci-datadog-action. Supported file patterns: package-lock.json,npm-shrinkwrap.json,yarn.lock

Justification:
yarn is available. why don't we use also pnpm?

Hi, @misogihagi 👋, Thank you for the feature request, we will investigate it and get back to you as soon as we have updates.

pnpm is already supported. per the project readme, specify cache.

[misogihagi]

My apologies.
I said something misleading.
Here is my code.

      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          cache: pnpm
      - run: pnpm install

It doesn't work because pnpm doesn't exist. yarn exists!

Similar to the #530 .

Why does yarn exist in default?

Yarn is in the GitHub runner images, while pnpm is not:

• https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2404-Readme.md

You could enable corepack or install pnpm with npm or Yarn. Or use this action:

• https://github.com/pnpm/action-setup

Thanks!
It seems to depend on the base image of the github action in question
I'll close it here.
